The Schedule referred to in these Letter Patent and making pari'. of the lame To all whoml it 'may concern "Beit known that I, ABRAHAM anrnonr, of 'the city, .couutyand State .of New York, have 'invented certain new and'usefniImprovements in Apparatus for Carbureting Airand Gases, of which the following isa full, clear, and exact description, reference being hadto the accompanying drawing forming part of this specification, and in whichf.-

Figure 1 represents a vert-ical section of a carbur-` eting apparatus having my improvements ap plied' to it, said section being tak'cn'as indicated by the line z x in .Figure 2, which is.a vert-ical section at right angles to fig.' 1 through the line y y', and

Figure 3 asimilar view through the line c z in tig; 1.

Figure 4 is a side view, on a larger scale, of an irregular shaped cam and variable spring-pressure 4attachment for operation in connection with the means .by lwhich the bellows of the apparatus are` driven, to prevent jump of the bellows at the period of the driv- ;ingcrank turning its centers.

Figules 5 and 6 are a face and sectional edge view of certain exible or rubber valves used in the apparatus; fig. 6 also showing the scat upon which the same are made to shut.

AMy invention is mainly applicable to `aqrpalatus in which the air or gas to be carbnretcd is forced by a bellows intoa reservoir capablcof distensiou and con` traction, from whence it passes to and through the carbureter, the bellows deriving their action from clock-work, or other-suitable power. s Buteeltain features of the invention are applicable to other descrip-` tions of carbureting apparat-us,

The invention consists in cY tain means, including anirTegular-shapcd cam and 1 fiction attachment nnder the control of a spring, for gradually checking and releasinghold on the driving mechanism" at' the period of tho drlvingcrankturningits centers iu the operation of the bellows, whereby jump of the bel. lows at such periods is avoided,.which steadies the ow of the air or gas, and, in the application of the apparatus to illuminating purposes, prevents unsteadiness of the lights.

The invention also includes a yielding spring-prcss ure applied to the movable portion of' the airreser voiruvhen distcndcd or at work,but distinct from any weight or force operating by the general action of the bcllows,'to expel the air or gas, and exerting uocon# trol ou the bellows till distended, said yielding springpressure vserving to prevent irrcgularflow of the gas.

The invention likewise includes a certain construct-ion or combinationof bellows having a center or dividing head and vibrating arm for operating the same.

The invention furthermore embraces a novel construction'of the carburcter proper, including an airchamber having a top or cover, and varionslydisposed corrugated and perforated plates arranged in stacks outside of the airs-chamber, with cotton;1wool or other absorbent material in between the plates, said top serving rto insure the air being forced'throngh the corrugated plates; also to spread the hydrocarbon liquid in its way tothe carbureter, and the corrugations in the perforatedplates. operating to break or divert through current, whereby the air is more per- 'fectly carhureted.

Referring to the accompanying drawing- A represents the bellows, which, though of a double action, is of single construction, being made u p of fixed heads aa, united by aiiexible body, b, which is divided by a center head, c, carried by or connected with a vibrating arm, d, that has its f 'ulcrum as 'at e.

Said arm is vibratcd, through a connecting-rod, f, by a revolving eccentric pin or crank, gthe shaft h ot'4 which derives its motion by gear that forms part of suitable clock-work B, which may be actuated by a weight. Y

i are the inlet vaives to the pump, and

ij the outlet-valves therefrom.

k k are the pipes which serve to convey the air from the bellows to th air-reservoir C.

These valves li 'i and j j, or `certain of" them, it is preferred to ednstruct of rubber or other suitable dexible material, hy-making, in a disk 'of said material, au incision which stops short of a complete circle, as shown in iig. 5,-

This is a simple way of constructing aapvalvc, and furnishes a fiange for securing the valve toits place. The valve-seat it is preferred to groove and ridge, as represented in iig. 6, whereby a tight titof the valve when closed is secured.

The air'reservoir C is composed of. a stationary lower head, lI, and upper movable head, m, united hy a flexible body, n.

The movable head Vm should be of suHiei'eut weight to insure the .requisite pressure with-in A the reservoir to force the air through the carbureter proper, and the carbureted4 air or gas from the latter through the delivery-pipes to tbeburners but, in addition to this provision, said reservoiris controlled, when distended, by ayielding spring-pressure applied to the movable head m of the reservoir, as by a detached spring, D, that is, a spring secured only at'oue of its ends, or of such a length that it is only brought into play after the'reservoir has been fairly distendcd,.v vhereby it is made toact with a gentle pressureand in a variable manuel', as contradistingnishcd from a weight which has a uniform force, for `the purpose of providing for any irregularity iu ,the' action of thc apparatus, as,

for instance, any irregularity in the motion ofthe bellows when turning theirVv center, and wherebyregulan it-y of flow is insured. y

To provide against-jump of the bellows when turning their center, and which produces uusteadiness of the' flame or flames at the burners, I apply to the driving-mechanism of the-bellows a iiictional device that acts in a. gradual manner as a temporary check, when the bellows are turning their center,

Said device consists of an irregularly-shaped cain, E, fast ou the crank-shaft h, or other shaft connected with the driving-mechanism, and soarrauged in relation tothe crank orV eccentric piu, from' which the bellows take' their motion, that 'the rounded or protruded surfaces of the cam come into contact with a: leather orrubber'friction-pad, F, as the bellowscrank orpin crosses its'center; but said cam, at othei'- peri` ods, being relieved from such frictional resistance, or only exposed to a very diminished lone. Y

For this purpose the cani E is niade with two rounded ends and two flattened or reduced sides, the: rounded l ends lying at right angles to the crank-pn, and to insure' an elastic action of the friction-pad F, it is hacked by a spring, o, and the latter preferably made adjustable, as regards its tension, by a setscrew, p. The cam E is thus made to 'exerta soft or easy and temporary check upon the driving-mechanism of ythe bellows wheu'turning the center, gradually letting up and go the same, and doing away wit-h all jump at such period or periods.

The carbureter proper, or generator, consists of a perforated air-chamber, G, covered -on .its top, -and having arranged outside of or around it, any number of stacks,-H H, oi'Jcorrugated and 'perforated cases or plates, q q, that may be variously disposed as regards the mounting of them, the'oue upon the other, but prcferahl y being arranged to alternately cross each other as regards their corrugations.

These corrugated and perforated plates containbe-A: tween them cotton, wool, or other absorbent material.

Said plates may be arranged within perforated cha1nbers, and have the brous material held between them,

saturated' with hydrocarbon liquid by"its admissionv through a supply-pipe, 1,-.onto a. properlyconstructed top, J,- over the air-chamber G, which top not only serves to prevent the air from escaping upward out of said air-chamber, 'andcompels it to pass through-be- `tween the perforated plates q q, but also answers tc conduct the entering'liquid to or over each stack of perforated plates, with their interposed absorbent material. Y

The air from the reservoir Gis admitted to the air# chamber G by pipes K and L, the latter being proair.

Introduced into the air-chamber G, which serves as vided with a cockr, to regulate the admission f the a distributer, the airiscnipelled bythe top J to pass Athrough the stacksH H ol corrugated plates, in order to find a vent or outlet, and in 'soy doing has its through course checked, or an undulating travel communicated to it, which materially aids its saturation with the hydrocarbon vapor, the increased area obtained by the corrugated construction ofthe plates 1,', of the pipe -L, above the junction of the pipe K, v -which extension forms the delivery-pipe for the carbureted air or gas-to the burners. v

Between this branch M and the pipe Kis acock, s,

Awhich, on being opened, serves to admit air direct from the reservoir C into the outlet or outlets which convey the carhureted air or gas to the burners to -miz'with said air or gas, whereby smoking at the fburners,J is prevented, and the lights may be regulated as desired, the cock r being simnltaneonslyregulated, if necessary, to .adjust the supply of air to the car'A .bureter. c

Of course the connections and arrangement of the cocks may be variously modified to produce the same eect without changing this feature of the invention, and'which provides for a flow of air from the reservoir C to mix with the carbureted air as it passes from the carbureter.
